Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rolling shutter door locks, in particular to an anti-theft lock for rolling shutter doors. Background Art
[0002] The rolling shutter door is a series of door panels with multiple joints. The door rotates up and down in a fixed slide with the scroll above the door as the center.
[0003] like Figure 1 As shown, the door lock of the existing rolling door is generally set at the center position below the rolling door. After the rolling door is locked, there is still a large gap between the bottom of the rolling door lock and the ground, which makes it easy for a crowbar to pass through the back of the rolling door lock to damage the rolling door lock, resulting in poor anti-theft performance and poor firmness. Utility Model Content
[0004] In order to solve the above technical problems, the utility model designs an anti-theft lock for rolling shutter doors.
[0005] The utility model adopts the following technical solutions:
[0006] A rolling shutter door anti-theft lock includes a door connecting piece and a ground connecting piece. The door connecting piece includes a fixed connecting plate, a lock seat and a sliding seat. One side of the fixed connecting plate is fixedly connected to the sliding seat. The fixed connecting plate is used to connect the bottom side of the rolling shutter door. The fixed connecting plate is installed with a lock seat. The ground connecting piece includes a U-shaped lock head part and a protective plate. The U-shaped lock head part is fixedly connected to the protective plate. The upper end of the U-shaped lock head part is inserted into the lock seat. The U-shaped lock head part is provided with a lock head connecting end. The lock head connecting end is horizontally provided with a row of lock holes arranged at intervals. The lock seat is correspondingly provided with a lock groove. A lock body mounting seat is provided on the outer side of the lock seat. The lock body is fixedly installed in the lock body mounting seat. After the lock body is locked, the lock tongue is output and inserted into the lock groove. The lock head connecting end is inserted into the lock groove. The lock head connecting end can adjust the horizontal position along the lock groove to complete the pairing of the lock hole and the lock tongue. The sliding seat slides on the slide rails on both sides of the rolling shutter door.
[0007] Preferably, the U-shaped lock portion and the protective plate are integrally formed from steel plates.
[0008] Preferably, the row of spaced lock holes are evenly spaced horizontally.
[0009] Preferably, a reinforcing rib is fixedly connected between the lock body mounting seat and the lock seat.
[0010] Preferably, after the U-shaped lock head portion is inserted into the lock seat, the protective plate covers the gap between the fixed connecting plate and the ground.
[0011] The beneficial effects of the utility model are as follows: when the rolling shutter door anti-theft lock of the utility model is locked, the upper end of the U-shaped lock head part cooperates to insert into the lock seat, and the protective plate covers the gap between the fixed connecting plate and the ground. When the anti-theft lock is in position, there is no obvious gap between the rolling shutter door and the ground for the crowbar to pass through, so that the crowbar cannot damage the inside of the anti-theft lock; the anti-theft performance is good and the firmness is strong.

[0017] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0018] Example: Figure 2-Figure 3 As shown, a rolling shutter door anti-theft lock includes a door connecting member 1 and a ground connecting member 2. The door connecting member includes a fixed connecting plate 3, a lock seat 4 and a sliding seat 5. One side of the fixed connecting plate is fixedly connected to the sliding seat. The fixed connecting plate is used to connect the bottom side of the rolling shutter door. The fixed connecting plate is installed with a lock seat. The ground connecting member includes a U-shaped lock head part and a protective plate 8. The U-shaped lock head part and the protective plate are fixedly connected. The upper end of the U-shaped lock head part cooperates to insert into the lock seat. The U-shaped lock head part is provided with a lock head connecting end 7. The lock head connecting end is horizontally provided with a row of lock holes 9 arranged at intervals. The lock seat is correspondingly provided with a lock groove 10. A lock body mounting seat 6 is provided outside the lock seat. The lock body mounting seat is fixedly installed with a lock body. After the lock body is locked, the lock tongue is output and inserted into the lock groove. The lock head connecting end is inserted into the lock groove, and the lock head connecting end can adjust the horizontal position along the lock groove to complete the pairing of the lock hole and the lock tongue. The sliding seat slides on the slide rails on both sides of the rolling shutter door.
[0019] The U-shaped lock head part and the protective plate are integrally formed of a steel plate. A row of lock holes are evenly spaced horizontally. A reinforcing rib is fixedly connected between the lock body mounting seat and the lock seat. After the U-shaped lock head part is inserted into the lock seat, the protective plate covers the gap between the fixed connection plate and the ground.
[0020] like Figure 4 As shown, the rolling shutter door anti-theft lock is arranged on both sides of the rolling shutter door, the door connecting piece is fixedly installed on the rolling shutter door, and the ground connecting piece is fixedly connected to the ground corresponding to both sides of the rolling shutter door. When the rolling shutter door anti-theft lock of the utility model is locked, the upper end of the U-shaped lock head part cooperates to insert into the lock seat, and the protective plate covers the gap between the fixed connecting plate and the ground. When the anti-theft lock is in position, there is no obvious gap between the rolling shutter door and the ground for the crowbar to pass through, so that the crowbar cannot damage the inside of the anti-theft lock; the anti-theft performance is good and the firmness is strong.
[0021] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
